To all whom, itmcty concern,.-

Be it known that I, ROBERT HILL, a citizen of the United States, and a resident ofLawchines for winding yarn, thread, or similar material upon tubular cops `by surface conf tact of the cop with an actuating-drum, the positive rotation of the latter acting by frictional contact with thecop and the gradually increasing thread or yarn mass thereupon to n rotate the same andeffect the winding. f In such machines the cop is mounted upon a ro.-

tatable holder or supportto be rotated therewith, the cops being made of paper, paste.-v

board, or similar material, forced upon the holder by the attendant when the winding is' about to begin and removed when the yarn or thread has been wound thereupon tothe desired extent. n

My present invention relates more particularly to the cop holder or support; and it has for its object the production of `a novel copholder, the construction and arrangement being such that the cop can be easily and quickly applied to and rmly held uponthe cop-holder without any twisting or forcingaction on the part of the operative. i

The variousnovel features of my invention will be hereinafter described, and (particularly pointed out in the following claims. y Figure 1 is a view, partly in velevation and partly in longitudinal section, of a cop-holder embodying one form of my invention,the supf port for the dead-spindle being shown. 2 is an enlarged side elevation, broken out and partly in section, of the cop-carrier detached;

and Fig. 3 is a transverse section, enlarged, on the line 00 0c, Fig. l.

' Referring to Fig. l, a dead-spindle d is provided with an enlarged flattened head ct', having a portion of` its perimeter flattened to present two faces a2 'c'the head being fulcru med on apin a4 between two parallelears ZJ, onlyone being shown, forming part of an arm or support B, of a construction well knownto Vsible thereat.

those skilled in the art. The outer end of the support is slotted or cut away at the base of and between the ears, as at bx, and a flat spring b', secured to the arm, bears at its free end on the fiat face a? of the spindle-head when the spindle is in full-line operative position, retaining the spindle in such position.

When the spindle is swung up into dottedline position to apply or doff a cop, the spring p engages the face a3, the support B being mounted on a part of the frame of a windingmachine adjacent the driving drum or cylinder. (Not shown.)

The `parts thusfar described are not of my `invention and are referred to only that the mode of use and application of the particular features involved in my `invention may be clearly understood. i

In accordance with my invention the cop -carrier consists of a metallictube C, of a length suitable for the cops to be used therewith, the tube being longitudinally slotted' at one end, as at cx, to render it radially expan- I have shownthe wall of the tube as somewhat thicker adjacent the expansible end, as at c, Figs. l and 2, and this thickened portion is interiorly screw-threaded at c to form an annular seat for a purpose to be described. `A sleeve or bushing c2 isforced into the tube from its opposite end to a point near the inner end of the seat, and it forms an intermediate bearing for and through `which the dead-spindle a extends.

An end bearing, shownas a short sleeve or bushing c3, is forced into the unslotted end of the cop-carrier C, forming an end lbearing.; therefor, said end bearing having, preferably, `a square external head ci and an annular flange c5, the latter projecting beyond the `exterior of the cop-carrier, while the head c4 practically butts against the circular portion of the spindle-head af, asinFig. l; The free Yend of the spindle is provided with a'longi tudinal threaded hole toreceivethe shank of a headed screw dx, Fig.`1, and a washer d loosely surrounds the shank ofthe screw'` between its head and the spindle and projects laterally over the outer end of theinterme-` diate bearing c2. The washer is inserted in ICO`` the cop-carrier before the bearings are driven into place, and after the spindle has been passed through the bearings the screw dx is An expander, shown as ashank e, Fig. 1,v

having a threaded portion e and a tapering head e2, is screwedV into the threaded seat c, and is therebysupported directly by and upon the cop-carrier, the tapered head e2 entering the expansible or slotted end of the cop-cairier. By screwing the expander in its tapered head engages the interior of the slotted end of the cop-carrier and expands it, the amount of expansion depending upon the inward movement of the expander, outward movement of the latter permitting the end of the cop-carrier to resume its normal diameter.

The cop-carrier C is well supported on the spindle a by or through the bearings c2 c3 and is freely rotatable when the spindle is in operative position; but when the latteris swung into dotted-line position, Fig. l, the head c4 enters between the parallel ears b and locks the cop-carrier from rotation.

A cop CX is shown in Fig. 1 in position on the cop-carrier, the flange c5 forming an end `stop for the cop, while the expansion of the cuter end of the cop-carrier securely and firmly holds the cop in place to rotate in unison with the cop-carrier.

Any suitable device may be employed to readily turn the expander to effect the securing or release of a cop, and I have shown in Fig. l a hole eX, polygonal in cross-section, in the end of the head e2 to receive a similarlyshaped key, (not shown,) with which the operative canlnanipulate the expander.

To apply a cop, it is slipped onto the copcarrier C, and a slight turn of the expander locks the cop securelyin place. When doffing, the expander is turned to permit contraction of the expansible end of the cop-carrier, and the cop can be easily drawn off.-

The device herein shownvobviates any forcing or crowding of the cop into place and does away with points, prongs, or other devices adapted to enter the cop to maintain it in po? sition. The length of the cop may be greater than that of the cop-carrier, so long as convenient access may be had to the expander to operate thesame.r Bymountingthe expander directly upon the cop-carrier the construction is simplified, strengthened, and cheaper to make.

Lubricant can be introduced to the bearings by a small hole C10, Fig. 2, in the cop carrier, and as the bearings are so inclosed and protected from the eect of dust and dirt but little lubrication is required.

My invention is not restricted to the precise construction show and described, as it lnay be modified in different particulars without departing from the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
